One-pot Electrochemical Formation of Meso,meso-Linked Porphyrin Arrays

Electrochemical oxidation of [5,15-bis(3,5-di-tert-butylphenyl)porphyrinato]zinc(II) 1, [5,15-bis(4-methoxycarbonylphenyl)porphyrinato]zinc(II), [5,15-bis(pentafluorophenyl)porphyrinato]zinc(II) or [10-bromo-5,15diphenylporphyrinato]zinc(II) in benzonitrile using a platinum net as the working electrode afforded the corresponding meso,meso-linked oligomer porphyrin arrays, and up to the octamer porphyrin array could be isolated for 1.
